这是我的php文件，用于提取我发送的所有数据
here's my php file where fetching all the datas that i'm sending
var_dump($_POST);
var_dump($_FILES);
顺便说一句，我在使用 var_dumping 时，图像文件没有任何问题.但它显示在 post var_dump 值中.
and by the way i have another problem the image file it gives me no result when i'm var_dumping it. but it shows
in post var_dump value.
我们严格使用本机 javascript ，我们不建议使用jQuery .或其他第三方.
We strictly using native javascript, we don't recommend using jQuery. or other 3rd party.
推荐答案
，而不是将请求标头放在ajax中.为什么不删除它?
instead of putting a request header in ajax. why not to remove it?
